Can anyone answer this please?

86

Step-by-step explanation:

1. Find the third interior angle of the triangle.

All angles in a triangle have a sum of 180 degrees. So, to find the third angle add the first two measurements and subtract their sum from 180.

28 + 58 = 86

180 - 86 = 94.

2. The inner angle and the outer angle are supplementary, meaning their sum is 180.

Subtract the inner angle's measurement from 180 to get the answer.

180 - 94 = 86

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6

2y+y=5

add 2y and y
